Dec. 28, 1948. o. R.'SIMMONS MATRIX DRYING AND ROASTING MACHINE 2 Sheets-Sheet '2 Filed June l9,- 1947 Inventor OscarR. Simmon Y Patented Dec. 28, 1948 This "inventiorr relates to new and useful improvements in matrix drying and roasting machines and theprimary object of the present invention is-to 'provide'a machine that will dry or roast paper matrices commonly-'iused for making stereotypeplates, insuch a manner that the entire surfaces of the matrices will be evenly dried or roasted. Another important object of the present inve'ntiorr is to provide a machinincluding a cylindrical ove'non which the matri is spirallywound as the" oven isrotated; I

A further object of the present invention is to provide a matrix drying and roasting machine embodying novel and improved means for rewinding the matrix that has been engaged upon the cylindrical heating element. a

A still further aim of the present invention is to provide a matrix drying and roasting machine that is simple and practical in construction, efficient and reliable in operation, inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended;

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a front elevational view of the present invention in use;

Figure 2 is an enlarged fragmentary side elevational view of Figure l; a

Figure 3 is a longitudinal vertical sectional view taken substantially on the plane of section line member or hollow roller forming a portion of an oven I8, are end plates 20 and 22 that carry bearings 24 and 26 which are journalled in side members [0 and 12 respectively.

One bearing, for example, 26, is hollow to receive a thermal controlled unit 28 which is connected in series to a plurality of longitudinally spaced ring coils 30 that are mounted within s IMATRIXI'DRYING'AND ROASTING MACHINE Simmons, Topeka, Kane: t

' Preferably, asbestos plates 32 are secured to the inner faces of plates 20 and 22 to permit only the curved peripheral area of member l2 to become heated. I 3 Fixedly supportedin bearings 34 at theupper ends of side members I 0 and His a shaft 36 is acoil spring: 44

' having one end fixed to the shaft; and the opposite end flxed to one of the end plates;

Removably secured to rollers 42 and member I8, are longitudinal retaining strips 46 and 41 that engage the respective marginal edges of a substantially rectangular asbestos blanket 48.

In practical use of the device, the blanket is spirally wound on the roller and the free marginal edge of the blanket is engaged with retaining plate 41 carried by member l8, so that the outer face of the blanket when wound on roller 42 will bear against the outer periphery of member l8.

A ring gear 50 carried by plate 20 is engaged by a pinion 52 at one end of a crank handle 54 journalled in a bearing 56 carried by the member I0, wherein the rotation of the crank handle causes a reduced speed rotation of member l8.

When the member I8 is rotated, the blanket is unwound on the roller 42 and rewound on member [8, with spring 44 in tension to return the roller to its normal position when the crank handle 54 is rotated back to its normal position, thereby automatically rewinding the blanket on the roller.

Obviously, a matrix may be inserted between the secured edge of the blanket and member l8 to be Wound on the member 3 as the same is revolved, thereby heating and roasting the matrix. As the roller rotates to its normal positionand as the blanket is rewound on the roller, the matrix becomes free and is readily removed from the machine for use.

It is possible from the foregoing structure, to windthe matrix upon the cylindrical member l8 with the use of the blanket.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims.

Having described the invention, what is claimed as new is:

1. In a matrix drying and roasting machine including a pair of side members, a hollow cylindrical member having end plates, heating coils mounted within said cylindrical member, and a spring tensioned roller journaled between said side members, bearings carried by the end plates of said oven rotatably engaging the side members, one of said bearings being hollow to receive a' thermal controlled unit for the-heating coils of said oven, an internally toothed ring gear fixed to one end plate of said oven, a crank handle carried by one of said side members, a pinion carriedby said crank handle: engaging gear, an electrical connection carried bysaid side member, conductive members carried: by said remaining end plate and-Jennnected tothe heating coils, saidconductive members engaging said electrical connection, and a shield carriedby said last mentioned side:member embracing and shielding said conductive members.

2. The combination of claim 1 wherein said heating coils include longitudinally spaced ring coils disposed within said cylindrical member, and asbestosplates carriedlby'theinner faces-of said end plates.

3. In a. matrix drying and roasting machine including a pair of side members, a hollow cylindrical roller having heating coils therein and a first end plate and a second end plate, and a spring tensioned roller Journaied between said side members, bearings carried by each of said end plates rotatably engaging said side members. the bearing carried by said second end plate being hollow, a thermal control unit positioned in said hoimw hnrmg'mr ttchaling coils, a ring gear bred to said first emi plate, a crank handle carried by one of said side members, a pinion carried by said crank handle engaging said, ring gear, an. electric plug carried by said remaining side member including conductive prongs. a 11b of conductive members carried by said second end plate engaging said prongs. and a shieid'can'iedby said last mentioned side member embracing and shielding said conductive members and said prongs.
